I do not think users on 3.6 are the right consumers for a STM release.
These users are conservative and did not ugrade earlier. I doubt they
are interested in new features *now*. Users that did not upgrade before,
are unlikely the users that will upgrade in three months when 3.9 is
EOL.

The packages from the CentOS Storage SIG will by default provide the
latest LTM release. The STM release is provided in addition, and needs
an extra step to enable.

I am not sure how we can handle this in other distributions (or also
with the packages on d.g.o.).
